GEORGE W. SHEPHERD, OF PHILADELPHIA, PENNSYLVANIA.

ELECTRIC GAS-LIGHTER.

fiPECIFICATION forming part of Letters Patent No. 540,463, dated June 4,1895.

Application filed March 13,1895- Serial No. 541,570. (No model.) I

To all whom it may concern:

Be it known that I, GEORGE W. SHEPHERD, a citizen of theUnited States,residing'in Philadelphia, Pennsylvania, have invented certainImprovements in Electric Gas-Lighters, of which the following is aspecification.-

view of a burner Fig. 2 is a front Fig. 3 is a plan view Fig. 4 is adetached view showing the binding-post.

A is the fixture composed of the hollow stem A, the crown A the screenor gauze a, the air valve A and the holder A The fixture shown is a.Welshbach burner of the ordinary construction.

B is the gas cook, in the present instance situated below the air valve.On turning this cook the gas will pass through the hollow tube A andmingle with the air in certain proportions and will escape through thegauze at which point it is ignited.

O is a mantel supported above the burner and inclosing a portion of thecrown.

I mount in suitable bearings secured to the holder, in thepresentinstance, a rod D which is attached at its upper end to a segmentd which passes partially around the burner above the crown, as shown inthe plan view. I preferably make a spring segment but it may be simplypivoted at one end and free at the other end.

On the valve stem 1) is a segmental cam b,

which is directly below the rod D and upon which the rod rides so thatwhen the valve is turned the cam will come into contact with the rod andlift it a certain distance, the rod being returned to its normalposition by a spring 2 which in the present instance is coiled aroundthe rod between the bearing and a collar which is detachably securedtothe rod.

Passing through the crown A is a terminal I, having a portion 1', whichrests over the free end of the segment at. This terminal passes insideof the crown A? and one end is connected to a binding post i" to whichis also connected a wire leading to the battery. The terminal I isinsulated from the crown and the binding post is insulated from theholder. On turning the valve the segment 61 is forced up in contact withthe portion 2' of the terminal I and when the cam releases the rod thesegment is drawn down by the spring creating the spark by which the gasis ignited.

It will be noticed that the burner is some distance away from the valve.Consequently to make the spark immediately on the turning of the valveit may not ignite the gas, but by making the cam on the valve as shown Imove the segment in contact-with the portion 11 and leave it there untilthe gas has time to flow through the tube to the gauze. Consequentlywhen the spark is made the gas is at the burner and can be readilyignited.

In order to detach the crown to replace the gauze the spring rod D andthe terminal I are made detachable so that they can be removed with thecrown.

I claim as my invention 1. The combination of the burner, having a crownand a screen, an electric terminal carried by the crown and a terminalring also carried by the crown, one terminal being insulated from theother, with means for moving one terminal toward and from the other tomake a spark, substantially as described.

2. The combination of the burner having a crown and screen, a segmentalterminaIattached to the crown, an L-shaped terminal overhanging thesegmental terminal and insulated from the crown, and means for movingthe segmentin contact with the L-shaped terminal, substantially asdescribed.

3. The combination in a burner having gas and air mixing tube, a crown,and screen within the crown, a shade holder, a segmental terminalattached to the crown, a rod secured to the segmentalterminal extendingdown through the shade holder, a spring tending to draw the rod down, agas valve, a long cam on the gas valve adapted to raise the rod, and anL-shaped terminal overhanging the segmental terminal and carried by butinsulated from the crown, the cam on the gas valve being of such alength that it will hold the terminals in contact until the gas hasreached the crown, substantially as described.

4. The combination of the gas tube, the screen, the removable crown, afixed terminal carried by the crown but insulated therefrom anddetachably secured to the conductor, a movable terminal also carried bythe crown and made detachable so that the head with the two terminalscan be removed from the t0 burner for repairs, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE \V. SHEPHERD.
